采用热丝法、X射线衍射(XRD)以及矿相方法研究TiO2对保护渣非等温结晶过程的影响.结果表明:枪晶石是含钛保护渣的主要物相.在综合碱度为1.3的基础渣中加入质量分数2%～8%TiO2后,随着TiO2的加入,渣样开始析出了少量的Ca2SiO4、Ca2Al(AlSi7O7)、Ca2SiO2F2和CaTiO3晶体.虽然加入TiO2,促进了析晶种类的增加,但保护渣的结晶过程的时间延长,且保护渣的结晶速率和结晶率降低.因此,加入TiO2后,抑制了保护渣的析晶,从而保证在控制渣膜热流的前提下,提高玻璃态的比例以改善润滑. The effects of TiO2 on the non-isothermal crystallization process of slag were studied by hot wire method, X-ray diffraction (XRD) and mineralogical method.The results showed that the gunite was the main phase of titanium-containing slag, After adding 2% -8% TiO2 into the base slag, a small amount of Ca2SiO4, Ca2Al (AlSi7O7), Ca2SiO2F2 and CaTiO3 crystals were precipitated with the addition of TiO2, although the addition of TiO2 promoted the increase of the type of crystallization , But the crystallization process of mold flux prolongs and the crystallization rate and crystallization rate of mold powder decrease.Therefore, the addition of TiO2 suppresses the crystallization of mold flux and thus ensures that the glass transition state Of the ratio to improve lubrication.
